What are the rules for traffic lights at intersections?

[VonEmersyn]

The rules for traffic lights at intersections are as follows: 1. When the green light is on: Vehicles are allowed to pass, but turning vehicles must not hinder the passage of straight-going vehicles and pedestrians. 2. When the yellow light is on: Vehicles that have already crossed the stop line may continue to pass. 3. When the red light is on: Vehicles are prohibited from turning left and going straight. When the red light is on, right-turning vehicles may pass provided they do not hinder the passage of other vehicles and pedestrians. At intersections without dedicated non-motor vehicle or pedestrian traffic lights, non-motor vehicles and pedestrians should follow the indications of the motor vehicle traffic lights.

As an experienced driver, I've encountered countless traffic light situations at intersections. When the light is red, you must come to a complete stop and must not proceed or stop beyond the stop line; when the light turns green, you can proceed, but you must first look around to confirm safety, paying attention to pedestrians and bicycles; the yellow light warns you to slow down and prepare to stop, not to accelerate and rush through. When turning right, some places allow right turns on red, but you must check road signs or signal indications and unconditionally yield to all through traffic and pedestrians crossing the street. Left turns require waiting for a green light, and if there is a dedicated left-turn signal, follow its instructions. When stopping at intersections, avoid blocking the crossing, especially during peak hours. If the traffic signal malfunctions, all vehicles should take turns to proceed to maintain order. These rules also apply in poor weather conditions, such as rain or fog, when you should slow down earlier. Following these basics not only helps avoid police fines but, more importantly, protects your safety and that of others. I always encourage everyone to be patient with each signal change and not to risk rushing for a few seconds.

As a parent, I teach my child traffic safety concepts through the rules of traffic lights at intersections. A red light means you must stop and wait, not crossing the white line to interfere with other vehicles or pedestrians. When the light turns green, proceed with caution, but I always instruct my child to first check for pedestrians crossing or obstacles in blind spots. A yellow light signals to slow down and prepare to stop, explaining that it's not a time to speed up. During family trips, I emphasize that right turns may sometimes be allowed on red at certain intersections, but safety always comes first—complete yielding is mandatory. Left turns require waiting for a green light and patiently looking for a safe gap. I use an analogy for my child: an intersection is like a shared space where everyone follows the signals to avoid conflicts. When stopping, don’t block the crosswalk, as it hinders pedestrian movement. Following these rules helps children develop good habits early, reducing accident risks. I also frequently remind them to be extra cautious with light changes when driving at night, ensuring clear visibility before moving.

Daily city driving to and from work involves simple yet often overlooked traffic light rules at intersections. A red light means you must stop—never rush through or halt in the middle of the road. When the light turns green, scan the entire intersection before proceeding, staying alert for sudden hazards. A yellow light signals immediate deceleration to prepare for a full stop. Right turns may sometimes be allowed at red lights depending on road conditions, but always yield absolutely. For left turns, wait for the green light and let straight-moving vehicles pass first. Avoid starting before the signal changes or stopping too far forward, which can block traffic flow. These rules keep intersections running smoothly, reducing congestion, especially during morning rush hours. As an ordinary commuter, I always remind myself to stay calm with every light change—driving neither too fast nor too slow, following regulations to ensure an efficient commute.
